New motherboard,New PC...who uses the optional extra software?

I have just had a new PC made with  the ASRockX79 extreme6 motherboard.I was wondering when you start up your pc do you use the extras that come with it? For example what came with the motherboard was  XfastUSB,Xfast LAN and a few other items that i have not decided do I need them or not.

 

I am finding my around the new PC,Win7 was not as scary as first thought....took to it like a duck to water :smileywink: and I am loving the speed.
